Hard folding bed covers that allow use of bed rails

It is difficult to tell from spec sheets and online info which hard folding bed covers allow you to retain and use the bed rails. Please post here if you know which ones do.

bakflip mx4?

toyota’s branded accessory bakflip?

Weathertech hard folding cover?

what about the hard style roll up cover?

 

I have the BakFlip MX4 and it does allow for the use of the bed rails, however I think there was a recent "update" that may have hindered that. I could be wrong though.

 

I have this one and can still use the tie down rails. Clamps for the cover do use the rail system so there are points on the rail you can't use.

I have the OEM Toyota tri-fold and it allows the use of the bed rails.

 

I have the MX4, but had to use smaller tie-downs I found on Amazon - the stock cleats were too big.

 

Big fan of my retrax xr pro versus the backflip it replaced.

 

does it allow the use of the bed rail system?

 

Sure does

 

Hard cover? That's a diamondback switchback. Rails are available under the folding sections.

 

I have the LoMax hardcover and I can still use the rails AND tiedowns
